Quick Start
Refer to the Figures shown for the hardware drawings which show the locations of
the switches, knobs, and jacks when reading the following, or even better, just look
at your unit.
1.
Connect the guitar to the IN jack, connect the STAGE OUT jack(s) to a power
amp such as the ISP Stealth which is connected to a guitar speaker cabinet, OR
connect the DIRECT OUT jacks to the input of a mixer, OR connect the
PHONES jack to headphones or earbuds (or connect all three). With a mono
system, the output(s) can be set to mono in the global parameters later. The
STAGE OUT jacks can be connected to a conventional guitar amplifier, but this
will not yield optimum results, since most guitar amps will further shape and
distort the sound.
2.
Connect the supplied 9V AC power adaptor to wall power, then to the POWER
input on the Theta Pro. The unit will power up and recall Preset 1. Pressing the
RECALL 1 switch will display the Preset 1 title.
3.
With the Preset title displayed, adjust the INPUT LEVEL control on the back
panel so that the LEVEL 0 LED (red) just flashes when playing hard, then back
off the INPUT LEVEL control slightly so that the 0 LED does not light. Short,
infrequent flashes of the red 0 LED are generally not audible. Adjust the STAGE
OUT LEVEL or PHONES LEVEL controls to taste. The DIRECT OUT levels can
be controlled by the global DIRECT TRIM parameter which affects all presets,
and by the OUTPUT LEVEL parameter within each preset, which affects all
outputs, but is the level specific to each preset. Note that the LEVEL LEDs only
display the raw input level when the preset or song titles are displayed
(FUNCTION turned fully counterclockwise). If any other parameters are
displayed, the LEVEL LEDs will display the maximum of the 4 output DAC
(Digital to Analog Converter) levels.
